<p class=MsoNormal><span style='mso-bookmark:OLE_LINK1'>The Screen saver
plug-in example demonstrates the usage of the ScreensaverPlugin API
(screensaverplugin.h) </span></p>
<p class=MsoNormal><span style='mso-bookmark:OLE_LINK1'>to implement an own,
customized utility screen saver on top of the default Series 60 screen saver.
The basic </span></p>
<p class=MsoNormal><span style='mso-bookmark:OLE_LINK1'>functionality of the
screen saver can be similar to the default screen saver but the appearance of
the activated</span></p>
<p class=MsoNormal><span style='mso-bookmark:OLE_LINK1'>screen saver can be
customized.</span></p>
<span style='mso-bookmark:OLE_LINK1'></span>
<p class=MsoNormal><![if !supportEmptyParas]> <![endif]><o:p></o:p></p>
<p class=MsoNormal>The default screen saver is designed so that it is easily
expandable with user plug-ins. </p>
<p class=MsoNormal>The same screen saver engine can support multiple different
plug-ins. This allows the user</p>
<p class=MsoNormal>to create many different-looking screen saver plug-ins and
the used plug-in can be changed</p>
<p class=MsoNormal>in the Themes application.</p>
<p class=MsoNormal><![if !supportEmptyParas]> <![endif]><o:p></o:p></p>
<p class=MsoNormal>This example draws a screen saver that contains a digital
clock, color-changing status indicator,</p>
<p class=MsoNormal>missed calls indicator(s), new message indicator(s), keylock
indicator, and used </p>
<p class=MsoNormal>profile indicator. </p>
<p class=MsoNormal><![if !supportEmptyParas]> <![endif]><o:p></o:p></p>
<p class=MsoNormal>Usually the status indicator is green, but if messages or calls
have arrived, the indicator</p>
<p class=MsoNormal>turns red. On the left of the status indicator there are
indicators for missed calls. There </p>
<p class=MsoNormal>will be as many device symbols as there are missed calls in
a row. On the right of the status </p>
<p class=MsoNormal>indicator there are indicators for new messages and they
operate in the same way as missed </p>
<p class=MsoNormal>calls indicators. The keylock symbol appears on top of the
status indicator. On top of all there is the </p>
<p class=MsoNormal>used profile indicator, which is visible if the device's
current profile is other than 'General'.</p>

<p class=MsoNormal>MScreensaverPlugin: </p>
<p class=MsoNormal>A base class that each screen saver plug-in must inherit and
implement. It provides, for example,</p>

<p class=MsoNormal>Known Issues</p>
<p class=MsoNormal>-------------</p>
<p class=MsoNormal><![if !supportEmptyParas]> <![endif]><o:p></o:p></p>
<p class=MsoNormal>A few bugs have been detected in the implementation of the
default screen saver</p>
<p class=00BodyText style='margin-bottom:0cm;margin-bottom:.0001pt'>of Series
60 Platform 2nd Edition (including Feature Packs 1 and 2). They are expected</p>
<p class=MsoNormal>to be fixed in the future releases of the Series 60
Platform. In this example some </p>
<p class=MsoNormal>workarounds have been introduced to overcome these issues.</p>
<p class=MsoNormal><![if !supportEmptyParas]> <![endif]><o:p></o:p></p>
<p class=MsoNormal>When the profile is set to other than 'General' and queried
with the API call</p>
<p class=MsoNormal>(GetIndicatorPayload(EScreensaverIndicatorIndexProfileName,
payLoad)), the</p>
<p class=MsoNormal>profile is returned ok. But after the profile is switched to
'General' and </p>
<p class=MsoNormal>queried with the API call, the payLoad.iText parameter is
not Zero()ed. </p>
<p class=MsoNormal>As a workaround, the example uses the CSettingInfo class to
receive correct</p>
<p class=MsoNormal>profile information in this situation.</p>
<p class=MsoNormal><![if !supportEmptyParas]> <![endif]><o:p></o:p></p>
<p class=MsoNormal>It was not possible to get the keylock indicator to work
using </p>
<p class=MsoNormal>GetIndicatorPayload(EScreensaverIndicatorIndexKeyGuardState,result)
of the </p>
<p class=MsoNormal>screensaverpugin API. Instead, the keylock status is queried
with the RAknKeyLock method.</p>
